What is cold shrink?

Cold Shrink Tube is a rubber tube that can shrink down 4-5 times smaller than its original size. Unlike heat shrink it does not require any type of heat in order to shrink in size, which is what called it the name “cold shrink.” If you’re familiar with heat shrink don’t let the “cold shrink” name confuse you.  Heat shrink requires heat to shrink but cold shrink does not require cold to shrink. The term “cold” is simply used to reference that no heat is required.


Cold Shrink is typically made of two types of rubber: EPDM or Silicone. You can easily find cold shrink manufactured from both materials and they both have their advantage and features. EPDM tends to be more wear resistant and capable of taking a beating, making it ideal for when the cold shrink is likely to be in contact with other materials, like inside machinery for example. Silicone on the other hand will shrink down to a much smaller and tighter size than EPDM, and is ideal for applications like cell tower weatherproof and sealing. We have an entire post dedicated to the differences between EPDM and Silicone Cold Shrink.Welcome to click here:

For the cold shrink tube,our small inner diameter can reach 13mm,the longest length can up to 1000mm now. All the product have full set of test report from SGS,such us IP68 waterproof,UV resistance,Ozone aging resistance,flame retardant. Cold shrink tubing are mostly used for waterproof sealing insulation purpose of cables, connectors, joints in telecom industry or electric power industry.
